Topics Covered in Exercise 8.3 Class 8 Mathematics Questions

Ex 8.3 class 8 maths chapter 8 focuses on the topics like multiplying a monomial by a polynomial, multiplying a monomial by a binomial, multiplying a monomial by a trinomial. Students can go through these topics to score good marks in exams.

1. Multiplying a Monomial by a Polynomial

• Multiplying a monomial by a binomial - To multiply a monomial with a binomial you have to multiply the monomial with each term of the binomial.

For example - multiplication of 5 and (x + y) will be (5x + 5y).

• Multiplying a monomial by a trinomial - Multiplying a monomial by a trinomial is also the same as above.

For example - multiplication of 4x and (2x + y + z) will be (8x2 + 4xy + 4xz).

Frequently Asked Questions

Question 1. Why are multiplying polynomials important in class 8 maths chapter 8 ex 8.3?

Answer 1. The property of distribution means that when we multiply polynomials, you can multiply each term on the first one by each term on the second one. you then combine the like words to make it easier. Some products have specific patterns that you can pick up and use instead of trying to multiply them all the time. In this exercise we will learn some differents types of methods to multiplying polynomials.

Question 2. What is multiplying a monomial by a binomial in ex 8.3 class 8 maths?

Answer 2. Multiplying a monomial with a binomial is when you have to multiply the monomial with each term of the binomial. For example, multiplication of 2x and (x + y) will be (2x2 + 2xy).
